Design feed entries that remain useful over time

Write the entry before the XML

Take one real article and describe its feed record in plain language. The title should identify the subject. The summary should explain why the article is useful. The link should open the complete page. The identifier should remain attached to this item even if the wording changes later.

The RSS specification defines guid as an item identifier. Keep your identifier policy explicit. A canonical URL can be practical when addresses are durable; a separate immutable identifier can help when migrations are expected. Whichever approach you choose, document it and preserve it during edits.

Use a field review checklist

• Title: does it make sense without the website's surrounding navigation?
• Summary: does it describe the actual article instead of repeating a generic site description?
• Link: does it load the intended page without requiring a temporary session?
• Date: does it represent the publication event accurately?
• Identity: will a correction keep the same item identifier?
• Content: do links and images work when displayed outside the website?

Handle corrections deliberately

Imagine publishing a guide titled “Publishing a release feed,” then correcting a mistaken command. Preserve the item's identity and original publication date. Explain a material correction in the article when needed. If the change warrants a separate announcement, write an update entry that clearly points to the corrected guide instead of silently pretending the original was newly published.

Do not rebuild identifiers from an item's position in a list. Adding a new first item would change the identities of everything beneath it. Similarly, a checksum of the complete article can change after a punctuation fix, making it a poor substitute for stable identity.

Validate meaning as well as syntax

An XML parser catches malformed markup; it cannot tell whether a summary points to the wrong article. Check a recent item, an old item, and one with unusual punctuation. Rebuild without changing content and compare the result. Unexpected changes to identifiers or publication dates deserve investigation before deployment. This combination of technical and editorial checks keeps a feed understandable as your publication grows.
